Rancho RS5000X Rear Shock for Jeep TJ and Wrangler

The Rancho RS5000X RS55240 is a rear suspension shock absorber for 1997-2006 Jeep TJ and Jeep Wrangler models with 0 inch raised height. It uses Rancho’s RS5000X valving approach and advanced compression control to improve on-road stability and off-road control.

Key Features

  • Rear shock absorber for 1997-2006 Jeep TJ and 1997-2006 Jeep Wrangler
  • RS5000X valving for balanced handling on pavement and trail use
  • Extended length: 20.04 in; compressed length: 12.76 in
  • Travel length: 7.28 in for suspension movement control
  • Dust shield included for added protection
  • Upper mount: cross pin mount with open-ended 3/8 in hole ID
  • Lower mount: loop bushing and sleeve mount

Product Details

Built for rear suspension service, the Rancho RS55240 shock is engineered around a reserve tube diameter of 2.188 in and a mount layout suited to the listed Jeep applications. The RS5000X line focuses on controlled damping through exclusive valving and compression tuning, helping the shock respond consistently during everyday driving and uneven terrain. For shoppers comparing Jeep TJ rear shock absorber options, RS55240 provides a direct-fit replacement path for the specified 0 inch raised height applications. This part cross-references Monroe Shocks & Struts (e.g., 37135) for the same application.

What It Helps Address

  • Excessive rear bounce after bumps or dips
  • Loose or unsettled rear-end feel on rough roads
  • Reduced control during off-road articulation
  • Worn shock performance from age and mileage
  • Inconsistent damping in rear suspension movement

Installation Notes and Tips

Verify rear fitment against the vehicle’s suspension configuration before installation. Match the upper cross pin mount and lower loop bushing mount to the existing hardware layout, and confirm compressed and extended lengths against the suspension travel available on the Jeep TJ or Jeep Wrangler. Because this shock is listed for 0 inch raised height, use it on the specified stock-height rear applications only.

Quality Assurance

Rancho positions the RS5000X line around controlled valving and improved compression behavior for dependable suspension performance. The RS55240 is built as a suspension shock absorber for the listed Jeep applications and follows the published mounting and dimensional specifications.
